Title: Double-acting hydraulic cylinder
Inventor: TAKADA KAN
IPC: F15B15/14
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity for providing a tube outside of a cylinder, and to prevent damage to a tube, and while to eliminate the regulation of arrangement such as direction by supplying the pressure oil to one chamber of an extension chamber and a contraction chamber, and at the same time, discharging the oil from the other chamber so as to telescope the full length. SOLUTION: Inside of a cylinder 1 is partitioned to an extension chamber 13 close to a base end block 2 and a contraction chamber 14 close to a cover body 3 by a piston 7. Pressure oil is supplied to one of these extension chamber 13 and the contraction chamber 14, and while the oil is discharged from the other chamber so as to telescope the full length. Since a piston rod 5 is formed into a hollow tubular shape and supply and discharge of the oil to/from the contraction chamber 14 is performed through the piston rod 5 and a supplying and discharging tube 17, which is inserted into the piston rod 5, the necessity for providing an oil supplying and discharging tube outside of the cylinder 1 is eliminated. Consequently, the peripheral surface of the cylinder 1 is formed into the simple cylindrical surface without generating a projection.

Title: Electrophotographic copying machine
Inventor: GUNJI KOICHI
IPC: G03G15/08
Filed: 1989-05-11
Abstract: PURPOSE:To shorten copying time by scanning a standard mark board part first, immediately returning and forming the latent image of the standard mark board part and an image part, erasing the formed latent image of the standard mark board and forming a margin part for filing at the time of selecting a filing margin copying mode. CONSTITUTION:When the filing margin copying mode is specified and a photosensitive drum 20 starts to rotate, a scanning optical system consisting of 1st and 2nd mirror units 6 and 9 scans the standard mark board 40 and the image is projected on the photosensitive drum 20 by a main lens 10 and a 4th mirror 11 to form the latent image 40a of the standard mark board. A controller allows the scanning optical system to return to an original position once to perform the scanning from the beginning, so that the latent image 40b of the standard mark board and the latent image 41a of an original are formed on the photosensitive drum 20 again. Furthermore, the controller erases an erasion range 44 including the latent image 40b of the standard mark board formed later. Thus, a copy with a margin for filing (h) can be obtained. Thus, the copying time can be shortened.

Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the transmission loss of a driving force to a main shaft conducting on/off of a switch, enhance reliability, and make the switch small by driving the main shaft by utilizing the rotation of a driving shaft of a rotary solenoid in the shaft circumferential direction. SOLUTION: A main shaft 2 of a switch is directly connected to a driving shaft 60 driven with a rotary solenoid 6, directly driven, a transmission part such as a link is made unnecessary, the transmission loss in the part transmitting the driving force to the main shaft 2 is eliminated, and operation is stabilized. By directly connecting the driving shaft 60 to the main shaft 2, an extra space is made unnecessary, a control mechanism part is made compact, a switch is made small. Since the driving part containing the rotary solenoid 6 is formed in a unit, the assembly time is reduced. Large inertia force in the switching-on direction by a weight 21 fixed to an inertial arm plate 20 acts to the main shaft 2. In the operation final period at which the driving force of the rotary solenoid 6 is weakened, this inertia force acts to surely conduct switching-on operation.

IPC: G02B5/04
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a laser beam projecting device capable of continuous focal adjustments using a simple mechanism. SOLUTION: A laser beam 5 emitted from a light source 1 impinges on two wedge prisms 2a, 2b. The wedge prisms 2a, 2b are arranged with their respective inclined surfaces 2u, 2v brought into contact and with their respective vertical surfaces 2w, 2x at right angles to the optical axis. A ball screw 2e is driven by a pulse motor 2f, and the prism 2b moves along the inclined surface 2v of the opposite prism 2a. As a result, the interval (composite thickness t) between the vertical surfaces 2w, 2x of the two prisms 2a, 2b varies continuously. Thus, since the optical path length can be varied continuously, continuous focal adjustments are made possible.
